Facing Hao Min's repeated questioning just now, Wu Han wanted to speak but stopped and turned to him. This strange situation naturally has a reason.

After providing some daily necessities for survivors in Xin'an Town, Wu Han suddenly discovered something that he had expected. There was not much salt in the warehouse. In fact, over the past year, including the usual pickled meat products, pickles and daily consumption, more than one-third of the total amount was spent in the kitchen of the scenic area and collecting salt from outside. Needless to say, the salt provided for Xin'an Town this time was equivalent to an additional consumption, and a salt shortage crisis naturally broke out.

Seeing that the salt was getting less and less, Wu Han was very anxious. Can people not eat salt? No salt is added to any dish, even if it is Tianjiu fin, abalone can’t taste delicious.

Although the salt in Peach Blossom Land will not be cut off in a short period of time, this difficult problem must be solved as soon as possible. At present, only Wu Han, who is in charge of the kitchen, knows the most about this matter. He is used to thinking about the whole thing first and then discussing it with others. Hao Min asked about it and was normal to be disappointed.

The hot spring in Taohuayuan is a high-salt hot spring, but the chemical composition of this spring is quite complex, and it is definitely not as simple as sodium chloride and distilled water. Because the spring water contains a large amount of salt compounds, the salt spring with complex ingredients cannot be dried like sea water and naturally becomes salt. The test piece produced by Wu Han secretly made the bitter and astringent taste so strange that his tongue and taste buds were paralyzed for a long time. Not only that, Wu Han also found that this salt also had side effects that cause diarrhea.

The situation is obvious. There is no problem with using salt spring water as bath water. If you eat it in your mouth without proper treatment, it will be so uncomfortable that it will feel.

It is said that Sun Meng and the other spoiled urban girls cannot accept it, and even if they are hardworking and endured, they still cannot withstand this torture. It has to be said that the appetite of modern people has been cured by the mechanism of salt. It is more uncomfortable to ask survivors to eat this salt with lower quality than industrial salt. It is not easy to use salt spring as raw material to process salt that suits the taste of humans. For the survivors of Peach Blossom Land, the time and effort required to be spent in the middle is a big deal.

I only regret that I have to use it when I use it! Unless it is an experimental course in the university's chemistry department, no one will think that they have learned how to make sodium chloride from complex salt compounds. Does this kind of daily necessities that can be bought anytime and anywhere require such a lot of effort?

Before the outbreak of the nuclear war, the salt industry in China was under strict government control and was a monopoly business commodity. Although the average cost of salt produced in the salt fields on the beach would not exceed 20 cents per catty, after an iodization procedure, the price of those iodized salts would exceed 1.5 yuan. It is really incredible. How high is the cost of iodization? It has to be more than ten times more reasonable. In addition to the private salt dealers who have been severely cracked down, most people will not sacrifice their lives with the state machinery in order to save this little salt money. Therefore, Wu Han's understanding of the salt-making process is basically at the initial stage of boiling seawater into salt.

"Magnesium chloride, magnesium sulfate, calcium sulfate, potassium chloride, calcium chloride, aluminum chloride, sodium carbonate... Oh my god! The earth! This ingredient is too complicated, there are at least dozens of impurities. When will we purify it?"

Flirting with the test vessel composed of irregular equipment such as glass cups, rice bowls, teapots, etc., and undertook a nearly professional level purification test. Several beauties complained. Wu Han, who came to visit the set with silage corn, expressed deep sympathy for their hard work, but he could not help. He shrugged and said:

"Oh, there's no way. Who told me to study hard? I don't know anything about chemistry. You guys can study it slowly! I'm only responsible for cooking and logistics support. We call it a professional and professional, and we can do our best."

Wu Han is just standing and talking without a pain in his back. Now some people quit. He has always been very clever and likes food. Zhao Yuan, who is nicknamed Diao Chan, spoke casually:
